Apple is about to make Hide My Email useless
Yesterday, June 15, 2026, a small and unimportant announcement appeared in Apple developer news: New domain for Sign in with Apple and iCloud+ Hide My Email.
Long story short: now both Sign in with Apple and Hide My Email aliases are going to be issued on the @private.icloud.com subdomain. This makes it much easier to ban all aliases without affecting non-relay mailboxes on iCloud mail.
This is certainly a big hit for iCloud privacy, since some plausible deniability together with Apple's backing made banning iCloud aliases costly.
